Abstract Objective: Alcohol misuse is prevalent and clinically significant among college students. Psychological distress is one factor that has been found to predict alcohol misuse in this population. However, relatively few investigations examined the association of psychological distress to alcohol misuse or its underlying mechanisms among students attending historically Black colleges and universities (HBCUs). The present study examined whether impulsivity explains the relation between psychological distress and alcohol misuse in this population using structural equation modeling. Methods: Participants were 287 undergraduate students attending an HBCU in the southern United States (Mage = 22.5, 66.3% female, 93.7% Black). Results: Impulsivity was found to significantly mediate the association of psychological distress to alcohol misuse, such that higher levels of psychological distress were associated with greater impulsivity which, in turn, was related to more alcohol misuse. Further analyses indicated that attentional impulsivity significantly mediated the association of psychological distress to alcohol misuse. Conclusions: These findings suggest the utility of targeting impulsivity in interventions aimed at preventing and reducing alcohol misuse among college students attending HBCUs who experience psychological distress.

一所历史悠久的黑人大学大学生中冲动性在心理困扰和酒精滥用之间的中介作用

摘要 目的：酒精滥用在大学生中普遍存在且具有临床意义。心理困扰是已被发现可以预测该人群中酒精滥用的一个因素。然而，相对较少的调查研究了心理困扰与酒精滥用之间的关联或其在历史上就读于黑人学院和大学 (HBCU) 的学生的潜在机制。本研究使用结构方程模型检验了冲动性是否可以解释该人群中心理困扰与酒精滥用之间的关系。方法：参与者是在美国南部就读 HBCU 的 287 名本科生（法师 = 22.5，66.3% 女性，93.7% 黑人）。结果：发现冲动性显着介导心理困扰与酒精滥用之间的关联，因此，更高程度的心理困扰与更大的冲动有关，而冲动又与更多的酒精滥用有关。进一步的分析表明，注意力冲动显着介导了心理困扰与酒精滥用之间的关联。结论：这些研究结果表明，在干预措施中针对冲动性的实用性，旨在预防和减少在经历心理困扰的 HBCU 大学生中的酒精滥用。
